 Pinus, New York and New England (Cke. Valsei of the U. S. No. 

 25\. The spermogonia are like the ascigerous stroma, only instead of 

 the black disk formed by the tips of the crowded ostiola, they arc 

 capped by a tubercujar-papilla which is at length pierced with a small 

 round opening, whitish-gray at first, finally darker. Spermatia 4 x 1 //.. 

 issuing in yellow cirrhi. 



The Newfield specc. agree perfectly with the European, only the 

 spermatia are about twice as long. Dr. Winter who examined the 

 specc. was of the opinion that the spermogonia did not belong to the 

 Valsa, \mt they are certainly very intimately associated. This species 

 is distinguished from V. Abietis and V. cenisia by its larger hemi- 

 spherical stromata and more numerous perithecia, but the three are 

 closely allied.

Stromata irregularly scattered, depressed-conoid, small, covered 

 by the subpustulate-elevated epidermis, which is pierced by the dense 

 fascicle of short, or sometimes elongated-cylindrical ostiola, which are 

 globose, smooth, black and densely crowded. Perithecia 5-15 in a 

 stroma, small, globose or angular from pressure, with very short necks, 

 buried in the unaltered substance of the bark. Asci narrow-clavate. 

 sessile, 25-32 x 5-6 p. Sporidia irregularly crowded, allantoic!, slightly 

 curved, hyaline, 6-9xlJ-lJ a. Spermogonia in stromata similar to 

 the ascigerous ones, multilocular, narrowed above and erumpent, with 

 a light-colored disk pierced by a single pore (rarely by several). Sper- 

 matia slender, 3 x 1 /i.

 of the country.

Stroma conic-truncate or depressed-hemispherical, covered by the 

 adherent epidermis, of a dark brown color, 1-2 mm. broad. Perithecia 

 2-20 in a stroma, subspherical or angular from mutual pressure, 

 densely crowded, with short necks and ostiola erumpent in a flat disk 

 or separate, short or subelongated, subcylindrical, rather stout, round-
